        (point))

The presence of such functions may reinforce the impression that they could be 
used as "beg" and "end" parameters to any other function that will process the 
text between "beg" and "end", in order to make it operate on the visual line.

This works for L2R or even R2L text, but as this thread has made clear, not in 
the bidirectional case. 

So one would want a warning in their DOC strings, if those functions are needed.
